Get a snapshot of the current state of the keyboard.
const Uint8* SDL_GetKeyboardState(int *numkeys);
|if non-NULL, receives the length of the returned array
Returns a pointer to an array of key states.
The pointer returned is a pointer to an internal SDL array. It will be valid for the whole lifetime of the application and should not be freed by the caller.
A array element with a value of 1 means that the key is pressed and a value of 0 means that it is not. Indexes into this array are obtained by using SDL_Scancode values.
Use SDL_PumpEvents() to update the state array.
This function gives you the current state after all events have been processed, so if a key or button has been pressed and released before you process events, then the pressed state will never show up in the SDL_GetKeyboardState() calls.
Note: This function doesn't take into account whether shift has been pressed or not.
This function is available since SDL 2.0.0.
